I have been running a pair of WD 7200 rpm drives in my laptop for the past year waiting for SSDs to get affordable. I see some of the 120 GB drives are not much over $200 now. I was wondering if anyone here had run a pair of them in RAID 0 and if there is any noticeable gain from doing so. I would like to get a pair of 120's but never having had an SSD I hate to make that investment yet. I am tempted to get 1 and do some testing. I believe the interface is SATA 2. Would I be exceeding the bandwidth of that with a pair of them? I am considering the Mushkin Callisto Deluxe and that is rated at up to 285MS/s read and 275 write. I don't want to buy 2 and set up RAID just to find that I would have been just as happy with 1.
